ABSTRACT
Objective To investigate the effect of radial artery hemostat (TR Band) continuous compression time on bleeding of puncture point, thumb perception, palm swelling and subjective comfort in patients undergoing transradial percutaneous coronary intervention. Methods One hundred and fifty-five patients who underwent transradial percutaneous coronary intervention were randomly divided into two observation groups and a control group. All patients in the three groups were treated by TR Band patent hemostasis. All three groups received the consistent deflation schedule, except the TR Band was removed at the 12th hour post operation in the control group, and at the 6th hour in the 1st observation group and at the 4th hour in the 2nd observation group. Postoperative bleeding of puncture point, thumb perception, palm swelling and subjective comfort were observed in the three groups. Results The differences of postoperative bleeding of puncture point, thumb perception, palm swelling and subjective comfort among the three groups were statistically significant (χ2=6.31, P<0.05; F=5.26, 4.00, 14.69, P<0.01). In the 2nd observation group, palm swelling was the lowest, but perception, and comfort and bleeding rate is the highest among the three groups. In the 1st observation group, the overall indexes were medium among the three groups. Conclusions The optimal compression duration of TR Band post transradial percutaneous coronary intervention is 6 h, which does not increase the risk of bleeding, but also significantly improve local swelling and perceptual experience, and increase patient comfort.
ABSTRACT
Objective To compare the clinical efficacies regarding femoral artery or radial artery approaches on coronary artery interventional therapies.Methods 360 patients were randomly divided into intervention group via femoral artery (TFI) or transradial coronary intervention (TRI) group.Postoperative observation on the two said groups of patients with vascular lesion characteristics,feasibility factors ( success rate of interventional therapy puncture,time of operation and hospitalization)and complications,were made.Results There were no significant differences between the two groups on the characteristics of vascular lesion (P＞0.05).Success rates of the two groups were 97.78％ and 96.67％ respectively.The differences on success rate,time of operation were not statistically significant (P＞0.05) while the average time of puncture,the mean duration of hospitalization and the rates of complications were significantly different ( P＜ 0.05 ).Conclusion The two methods under comparison had similar success rate and feasibility.However,the complications related to radial artery interventional therapy were much less than the femoral artery interventional therapy.As having better safety,radial artery interventional therapv seemed to have applicable value on clinical oractice.
